Hi all, I have not been lurking or posting much due to the computer/user ratio here lately but that can be a seperate thread.
A friend gave me a box of old tools that I can't quite figure out .
I do not have a digital camera so I'll have to describe as best I can.
Watts Bros. Tool Works in Pa. patented them 9/25/1917 or so it is stamped on them, but Google did not turn up anything.
The driver/holder resembles a drill chuck,with a morse taper shank then a body that houses a tool holder that moves lateraly but is '' driven'' by the shank. The various sized tools look like a crude five fluted reamer, but the flutes are not sharpened, except on the end like a end mill. Size is marked on them , e.g. 1-1/64 .
I put the set up in the lathe and tried it out on a piece of alum. scrap bar stock, and it needs a pilot hole or it just chatters.:confused:


Thanks,
Steve

Harry Watts designed a drill in 1914 with a patented "full floating chuck" to accommodate his irregular bits. Bits for square, pentagonal, hexagonal and octagonal holes are still sold by the Watts Brothers Tool Works in Wilmerding PA. The actual drill bit for the square is a Reuleaux triangle made concave in three spots to allow for unobstructed corner-cutting and the discharge of shavings

Sounds like a hex drill to me. There should be a guide for it, but the 5-flute cutter goes into the 6 corners by a kind of orbiting motion. That would be why the thing can move somewhat on the shank.

<edit> Ah, Tinkerer beat me to it.

I burned nearly an hour of precious computer time with patent searching on Google ,etc. and I get two great replies in less time than it took to try to make the description make sense,thanks a bunch! Now all I have to do is master drilling square holes:D

No you didn't but unfortunately you misspelled the word "these" and that probably means no one will be interested. You also booted the buis when you likely meant the old colloquial term of biz! You're gonna be judged hard on this so get ready to take some incoming flak :D :D

I am curious. Has anyone used one of these that can report on how well they work?

Best,

You need the whole (hole?) thing.

The guide is also needed. here is a guide plate and drill, obviously for a square hole.

O.K. , here goes I think I Might have a pile of guide plates somewhere also but I am not sure. As soon as I get a chance I'll look. I have to try to find time to sneak on MY computer between my wife and two kids MORE IMPORTANT tasks that never leave me any log on time. I knew that there was a reason this stuff stayed out of the scrap iron bin, I just didn't know what it was untill now.:)
